One generated day
Every angler in a tournament fishes the same deterministically generated lake — same fish in the same places, same weather, same schedule.
The premise
Nothing is random
between players.
Randomness still exists in the water. It is identical for every entrant, so it cancels out of the result. What is left is decision quality and execution.
The server re-fishes it
Your client sends your inputs, not your score. The server replays those inputs through the same simulation and computes the result itself.
Instruments, never conclusions
Every input to fish behaviour is something you can observe before you act on it. The game shows what an angler could measure — never where the fish are.
A tournament day
Two hours on the water.
Read the day
Temperature, thermocline, oxygen floor, clarity, wind, period — each labelled with where it came from and how well it is known.
Pick your water
Travel and trolling-motor nudges charge the clock in lumps. Everything else runs in real time. Where you spend the day is the first real decision.
Work the lure
Cast, then work it back — jig, pause, speed. A fish that commits follows the bait until it bites, spooks, or the lure reaches the boat.
Best five
Hookset, drag, line tension, landing. Keep five, cull the light ones, and weigh in against everyone who fished the same water.
The water
Real lakes, built from
public survey data.
Each lake ships a depth grid, a land heightmap, ground-cover classification, aerial imagery and a biological profile — assembled from public-domain government geographic data.
Missouri
Smithville Lake
7,190 acres just north of Kansas City. Bass and crappie around timber and brush.
Oklahoma
Grand Lake
Grand Lake O' the Cherokees. Deep creek arms, rock and dock structure across a long impoundment.
Texas
Lake Fork
Standing timber and a trophy reputation. Fork is the benchmark water for a big-fish day.

Adding a lake is a documented procedure here, not a bespoke build.
The observability rule
If it changes the outcome, you can see it before you act on it.
A hidden variable that moves results is indistinguishable from luck. So bass behaviour runs on things you can measure — season, water temperature, an oxygen floor, thermocline, light and period of day, clarity, wind, forage by season, the pressure you yourself have put on the water, and a per-fish hunger clock.
Six assists can carry the mechanical load — hotspot glow, assisted cast, retrieve cadence, hookset, drag, culling — and not one of them reveals anything the water didn't already tell you.

Gear
A choice, never
an advantage.
Every player carries the same tackle box. Each lure is scored on six integer axes and matched against what the water under the boat is asking for. The right lure beats the wrong one by up to three times on presentation — but everyone owns the whole box, so the difference is a read, not a purchase.

Boats, outboards, trolling motors and fish finders are on the rig for the look of it. At launch every rig item resolves to identical values — no item is an advantage.
